  11. Definition • Airflow obstruction • Bronchial hypersensitivity • Underlying inflammation

  12. The causes • Environment pollution • Genetic inheritance • Immune system problems • Combination of factors can lead to or exacerbate asthma

  13. Symptoms • Recurrence of chest tightness • Coughing • Shortness of breath • Wheezing • Asthma attack

  14. Condition

  15. Control the symptoms • There is no cure, but the symptom can be controlled and managed. • Appropriate use of asthma medication • Avoidance of environmental irritants • The frequency and severity of asthma attacks can be lessened.

  16. Asthma care • Asthma care begins at the time of diagnosis and should continue with ongoing followed-up care. • Controlling factors causing asthma severity • Assessment • Monitoring • Pharmacotherapy • Education for asthmatics

  17. Suggestions • Not smoke & not take cough medicine without consulting a doctor. • Not use non-prescription inhalers • Non-prescription inhalers may contain short-acting drugs that may not last long enough to relieve an asthma attack and cause side affects. • Aspirin and nonsteroidal anti-inflammatory drugs such as ibuprofen can cause asthma to worsen in certain individuals.

  18. Summary • Asthma is a long-term disease but it is manageable. • Medical treatment during the early stages of an attack is very important. • The patient’s active involvement on treating this disease is vitally important.

  19. Discussing-1 • How come the proportion of asthmatics rise in the recent decades?

  20. Discussing-2 • If you suffer from asthma, what kind of life/treatment will you choose? • Will you live in the fear of “asthma attack” ?

  21. Supplement reading:Oil spill’s human health impacts might extend into the future

  22. The Mexico oil spilling

  23. The Moxico oil spilling

  24. Brainstorming • What impacts does oil spilling put on to the environment?

  25. Brainstorming • What impacts does oil spilling put on to the human?

  26. Main idea • The physical health problems caused by the oil spilling • Breathing difficulties • Skin irritation • DNA damage • The psychological ailments • Higher rate of depression • Anxiety • Posttraumatic stress disorders

  27. Vocabulary-1 • Crude oil [rɔt] (n.) • a dark oil consisting mainly of hydrocarbons • Dermatitis [͵dɝməˋtaɪtɪs]  (n.) • inflammation of the skin; skin becomes itchy and may develop blisters • Volatile  [ˋvɑlət!]  (adj.) • evaporating readily at normal temperatures and pressures; "volatile oils"; "volatile solvents" • Dissipate [ˋdɪsə͵pet]  (v.) • to cause to separate and go in different directions

  29. Spill-related symptoms • More than 300 people had come forward with Spill-related symptoms • Chest pain • Coughing • dizziness • Headaches • Respiratorydistress • Vomiting • It is difficult to clinically distinguish toxic symptoms from other common illness.

  30. Damage caused by VOCs • Respiratory problems • Temporary central nervous system troubles • Cancers • Dermatitis & skin infection

  31. Supporting literature • Scientist combed the literature for clues about long- and short-term impacts • 270 people who work on clean-up of the Exxon Valdez spill filed claims for respiratory problems. • Those who worked most closely with the spilled oil had “a greater prevalence of symptoms of chronic airway disease," ”

  32. Spill-related health damages • Workers & volunteers • Exposed to the most VOCs evaporating from the light oil floating on the ocean surface • Exposed to compounds from chemical dispersants being used • Contact with weathered oil, which clumps up and can coat beaches and animals

  33. Spill-related health damages • Residents in the affected communities are also at risk of • exposure to wither crude oil in the water or weathered oil on the beach • Inhalational exposure to chemical compounds • Eating potential contaminated sea food

  34. Spill-related psychological ailments • The psychological ailments prompted after dealing with spilling • Higher rate of depression • Anxiety • Posttraumatic stress disorders

  35. Conclusion • “The impact of frequent natural and human-caused disasters such as Hurricane Katrina and now the oil spill, further strains populations that are already experiencing a great deal of stress." • “Psychological and social impacts may be as significant as the physical impacts of the Gulf oil spill.”

  36. Discussion-1 • Why do people suffer from psychological ailments after the oil-spilling disaster? • What is the deeper meaning?

  37. Discussion-2 • How can we approach to the balance between Nature & Culture?

  38. Discussion-3 • How will our future world become?
